A Review on Airflow and Temperature Distribution in A Residential Building with an under Floor Air Distribution System

This paper presents the investigation to evaluate an under floor air distribution (UFAD) system existed in a Residential building. Despite the fact that UFAD systems are being applied in the field in increasing numbers, there is a strong need for an improved fundamental understanding of several key performance features of these systems. Recent trends in today's Residential environment make it increasingly more difficult for conventional centralized systems to satisfy the environmental preferences of individual persons using the standardized approach of providing a single uniform thermal and ventilation environment. 

Under floor air distribution (UFAD) is an air distribution strategy for providing ventilation and space conditioning in buildings as part of the design of an HVAC system. UFAD systems use an under floor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air through floor diffusers directly into the occupied zone of the building. Thermal stratification is one of the featured characteristic of UFAD system, which allows higher thermostat set points compared to the traditional overhead systems (OH). 

CFD models have been used to study indoor air quality (IAQ) problems, pollutant distributions, and performance of UFAD systems. The increasing developments of computational fluid dynamics (CFD) in the recent years have opened the possibilities of a low-cost, yet effective, method for improving UFAD systems in design phase, with less experiment required.

A Review on Performance Enhancement of Catalytic Conveter by Making Geometrical Changes

Now a days the global warming and air pollution are big issues in the world. The 70% of air pollution is due to emissions from an internal combustion engine. Catalytic monolith converters have been used for nearly four decades to reduce the toxicity of exhaust gases from the internal combustion engine powering automotive/machines The harmful gases like NOX, CO, unburned HC and particulate matter increases the global warming, so catalytic converter plays an vital role in reducing harmful gases, but the presence of catalytic converter increases the exhaust back pressure due to this the volumetric efficiency will decrease and fuel consumption is higher. 

So analysis of catalytic converter is very important. The scarcity and high demand of present catalyst materials necessitate the need for finding out the alternatives. So this paper is based on to find the possibility regarding to reduce emission and converted into high rate.

Enclosure Design for 3D Printing

In the recent past many industries have widely started adopting 3D Printing for prototyping and manufacturing of low volume customized parts. This paper will look at additive manufacturing or 3D printing and how electronic enclosures can be developed using this technology. It will define the meaning of this term and what is so significant about it. It will delve a bit into its advantages, compared to conventional methods of manufacturing and its types. Then finally we will discuss the steps involved in design of these enclosures and some guidelines while designing them for 3D printing.

Effective Printing Text using Bluetooth Technology from Android Application

In communication Bluetooth technology is becoming popular standard, in wireless technologies it is one of the most expeditious growing field. It is very facile to utilize and can meet most of today's injuctive authorizations of mobile and personal communication wireless part of this communication is handled by Bluetooth. Between these contrivances it transmits and receives data. While mobile phone is not just a phone these days. there are no of applications used in mobile wireless printing. its quite popular to print from a mobile applications. 

this paper aims to do that. in market each of printer company has its own printing application. the main aim of this work is to develop only android application for all printers as to implement real time thermal printing from mobile application even through voice command.

Effect of Static Load on Cast Iron Drainage Manhole Cover

Drainage manhole covers are widely used in sanitary sewer and storm water systems in world. However, technical information regarding their structural aspects is limited. The main objective of this paper is to evaluate the effect of main parameters that impact the design of manhole cover. A three-dimensional finite element model for circular manhole cover was developed using AutoCAD, solid works and NX. The 3d model was analyzed by ANSYS for different parameters like different load and different material. Here cast iron is used as material of cover. The load condition was applied for two type of cover one without stiffer and with stiffer.

Performance Evaluation of Radon Mitigating Materials for Building a Radon Resistant Dwelling

Radon mitigation performance of SGMs and ARMs was evaluated in five different modes, two of which are active modes supported by a ventilation fan on and the others are passive modes with no fan. The test was performed in a concrete structure consisting of eight partitioned rooms. The bottom side of each room is covered with gravels and radon gas soil sampled at nearby open fields. Then, SGMs and ARMs are installed on top of the soil to block the radon gas. 

The test is performed for three days in passive modes and for another three days in active modes. Then, the radon concentration is measured with an E-perm monitor. These tests are repeated for three different levels of radon gas concentration in the sample soil, labeled as low (L), medium (M) and high (H). Experimental results present two observations. The first one is that, in accordance with the EPA recommendations, radon mitigating materials make much greater effects when they are used in an active mode. 

The best result was from A-1 mode (SGM+ARM+fan). For all of L, M and H soil samples, the radon concentration turned out to be the lowest, about 10 % ~ 40 % of 148 Bq/m3, the EPA activation level (EAL). In A-2 mode (SGM+ fan), the concentration was a reasonably fair level, about 25 % ~ 48 % of EAL. The second observation is that the performance of mitigating materials used in passive modes is unreliable. In all of three passive test modes, the radon concentration was higher than the EAL, or just below the EAL.
